Some quick googling suggests the answer: It's behavior defined by the
servlet spec.  See Section 3.1.1.  When it's
"application/x-www-form-urlencoded", then essentially any call to any of
the request getParameter* methods prior to calling getInputStream()
results in the request body being consumed, in order to populate the
request parameter set with the form params.  After that, the body can no
longer be read, so the input stream is null or at least the i/o cursor
is at the end of the stream or something.

We are not calling getParameter() that I can see, but I imagine
something in the MVC or SWF layer is (like make checking for flow
execution key or something?).  So that pretty much explains it I think.
